4 Roll Plate Bending Machines

Product Code: 4R SBS

4 Rolls Hydraulic Sheet Plate Bending Machine

4 Rolls Hydraulic Plate Bending Machine is one of the hydraulic roller machines used in the industry for bending thin or thick sheet plate curling at the desired inclination. This machine is ideal for forming full circle, semicircle, conical, oval and radius shapes.

Design and Structure

Equipped with an advanced design, the 4 Rolls Hydraulic Sheet Plate Bending Machine has a sturdy frame and hydraulic safety chuck that allows easy removal of part roller settings from the control panel. Furthermore, all rollers are hardened, which increases the durability and longevity of the machine.

Working Principle

4 Rolls Hydraulic Sheet Plate Bending Machine is equipped with four roll technology and again bending capability. This makes it possible to produce sheet plate curling tubes that can be welded with a laser longitudinal seam welding machine. The metal workpiece is securely fixed between the upper and lower rollers, while the side rollers move vertically to form a bending. The bottom roller holds the sheet plate curling profile or plate surface securely against the top roller, while the side roller is raised to create a pre-bending, minimizing the flat area at the edge of the workpiece.

Technical Specifications

4 Rolls Hydraulic Sheet Plate Bending Machine has fixed positioned top rolls and two offset or lateral rolls, one on each side.
Under the top roll, there is an additional roll that continuously clamps the plate during rolling and can pre-bending both ends of the workpiece (sheet plate curling or profile).
4 Rolls Hydraulic Sheet Plate Bending Machine, the sheet work piece is held securely between the top and bottom rollers, while the side rollers move vertically to form bendings.
4 Rolls Hydraulic Sheet Plate Bending Machine is loaded horizontally at the feeding level for pre-bending. This allows the use of horizontal motorized roller tables to assist in feeding the workpiece.

This part is the first step of machine production process and it contains making needed calculations of machines, drawing these machines on CAD programs like AutoCAD and Solidworks to see integrated productions as 3D dimension virtually and analysing machines. Currently, we have 2 Solidworks CAD program - one of them is with structurel analysis module-. Machines are designed as 2D and 3D for controlling capabilities of machines visually

Design process is not proceeding only with one person. Just in case possibility of being some mistakes or improvements, meetings are set for review of design and different options for improvements are considered by taking support of analysis program as well. Then, it is approved for passing next step of production process.

One of the steps before starting machine production is procuring necessary materials according to product tree list that is decided in design step. In this step, flat plate products, steel of shafts, brass blocks, hydraulic cylinder materials etc. are procured.

These are the components that have manufactured, have been manufacturing or procured from marketplace and ready to use in the assembly part. These components can be classified as Electrical Unit, Hydraulic Unit, Reductor, Ball Bearings etc.

In this step of the process , these kind of works are carried out ; for completed machine elements as schematically and constructionally, being taken technical drawings and forming some parts which are needed, with the aid of various cutting tools.

Raw materials that have been procured as sheet metal in different dimensions and specifications, are cut according to drawings that prepared in design step , by using CNC Plasma Machine.

In this step, some specified parts in the desing step are welded properly after machining or cutting step to make it ready for assembly.

This is the last step of manufacturing process and in this step, all parts are assembled. Then integrated machine is obtained.

After production of machine, another very important case that controlling the machine. So, in this step machine is tested to verify reality of datas that obtained theoritically and in virtual system. This step includes all parts of machine. Firstly, controlling is started from electrical equipment. The electric panel, valves and other electrical parts are tested. Then, movements of pistons and leakage of hydraulic oil are checked over. Finally, the material which will treated, is placed to machine properly and it is worked on material to test for general tests of machine.

After all tests are done and datas are confirmed, machine is ready for delivery.
